0eba65d201 boards: lx2160a: Add support of I2C driver model
DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C
API when DM_I2C is used. When DM_I2C_COMPAT is not enabled for
compilation, a compilation error will be generated. This patch solves
the problem that the i2c-related api of the lx2160a platform does not
support dm.

This driver uses bss from SPL board_init_f(). Change it to move all the
data from bss to a common struct allocated on the stack (64 byte).

In addition to saving 28 bytes of bss, the code even gets 264 bytes
smaller.

29873c74f3 arm: socfpga: move gen5 SDR driver to DM
To clean up reset handling for socfpga gen5, port the DDR driver to DM
using UCLASS_RAM and implement proper reset handling.

This gets us rid of one ad-hoc call to socfpga_per_reset().

The gen5 driver is implemented in 2 distinct files. One of it (containing
the calibration training) is not touched much and is kept at using
hard coded addresses since the code grows even more otherwise.

SPL is changed from calling hard into the DDR driver code to just
probing UCLASS_RESET and UCLASS_RAM. It is happy after finding a RAM
driver after that.

88c3bb49e1 ddr: socfpga: Clean up ddr_setup()
Replace the current rather convoluted code using ad-hoc polling
mechanism with a more straightforward code. Use wait_for_bit_le32()
to poll the DDRCALSTAT register instead of local reimplementation.
It makes no sense to pull for 5 seconds before giving up and trying
to restart the EMIF, so instead wait 500 mSec for the calibration to
complete and if this fails, restart the EMIF and try again. Perform
this 32 times instead of 3 times as the original code did.

8297dd1d93 ddr: socfpga: Clean up EMIF reset
The EMIF reset code can well use wait_for_bit_le32() instead of all that
convoluted polling code. Reduce the timeout from 100 seconds to 1 second,
since if the EMIF fails to reset itself in 1 second, it's unlikely longer
wait would help. Make sure to clear the EMIF reset request even if the
SEQ2CORE_INT_RESP_BIT isn't asserted.

This syncs drivers/ddr/marvell/a38x/ with the mv_ddr-armada-18.09 branch
of https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git.
Specifically this syncs with commit 99d772547314 ("Bump mv_ddr to
release armada-18.09.2").

The complete log of changes is best obtained from the mv-ddr-marvell.git
repository but some relevant highlights are:

  ddr3: add missing txsdll parameter
  ddr3: fix tfaw timimg parameter
  ddr3: fix trrd timimg parameter
  merge ddr3 topology header file with mv_ddr_topology one
  mv_ddr: a38x: fix zero memory size scrubbing issue

The upstream code is incorporated omitting the portions not relevant to
Armada-38x and DDR3. After that a semi-automated step is used to drop
unused features with unifdef

The SDRAM must first be rewritten by zeroes if ECC is used to initialize
the ECC metadata. Make the CPU overwrite the DRAM with zeroes in such a
case. This scrubbing implementation turns the caches on temporarily, then
overwrites the whole RAM with zeroes, flushes the caches and turns them
off again. This provides satisfactory performance.

e6fce12d14 ARM: mvebu: a38x: move definition of PEX_CFG_DIRECT_ACCESS
PEX_CFG_DIRECT_ACCESS was defined in ddr3_hws_hw_training_def.h despite
only being used in the serdes code. Move this definition to ctrl_pex.h
where all the other PEX defines are. Also remove the duplicate
definition of PEX_DEVICE_AND_VENDOR_ID which is already defined in
ctrl_pex.h.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

d024236e5a Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR
We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

944537c56e drivers/ddr/fsl: Modify binding registers to save time on data init
DDR controllers always use binding register to determine the memory
space to perform data initialization. In case of controller interleaving,
the space is doubled, resulting twice long wait. It wasn't too bad until
the memory capacity increases. To reduce the wait time, reduce the
binding space to half and restore it after data initialization.
Three-way interleaving is no longer used and is removed.
